9 JANUARY 1959 FLIGHT 37 Pe-Ieing Protection WITH A DIFFERENCE MICROGRAIN A new type of nickel deposit, MICROGRAIN, which is extremely hard yet flexible, has been developed for the protection of aircraft de-icing equipment. Tests show that MICROGRAIN propeller-edge and air-intake electroformed sheaths are so highly resistant to damage and deformation by dust, stones and rain erosion at impact speeds of up to 500 m.p.h. to be in all respects superior to stainless steel for de-icing equipment protection. Fatigue tests have shown that the material has a higher fatigue strength than the component to which it has been fitted. The most recent tests in resistance to erosion by water show no apparent effect on the surface of the nickel under conditions of a supposed component flying at the above speed through rain at 3in per hour for 35 hours. DALIC This process is widely used throughout the aircraft industry for the re-zinc plating of damaged propeller blades. Rhodium plating of commutators is an additional function of this process. The advantages to be gained by Rhodium plating are that the metal has a low electrical resistance, is non-oxydizing and has a hardness of 5-600 Brinell and a lower coefficient of friction than that of copper oxide. The DALIC technique obviates the numerous difficulties experienced in bath plating a complete wound armature.
